GByteArray* to char*

[joshshamir]

Hi,

could someone give me a code snippet of a function that takes a GByteArray (glib.h) as input and returns a char* buffer as output

char* convert(GByteArray* b, int* offset);

I need to pass the buffer obtained above to the

int EVP_DigestUpdate(EVP_MD_CTX *ctx, const void *d, size_t cnt);

function

Thank you

char* ffff(GByteArray* b, int offset) /* why int*? */
{
   return (char*)b->data + offset;
}

Why not if GByteArray is:

I'm not sure. I never used glib...

Thank you,
int* offset is a pointer to int used to store the number of bytes that were already read in the GbyteArray.
This pointer indicates the exact point in the GbyteArray from which the conversion function (GByteArray to char*) can start to read.

I want to add that I've tested your function but always return an empty string.

Any idea?

Thank you
